Solar mode:
The solar function can be used directly without installing batteries, and the brightness is automatically adjusted according to natural light (the red dot scale cannot be switched).
To switch the red dot scale in solar mode, you need to open the side battery compartment and install the CR1632 battery, then press the "▲" button to activate it, and then press the "▲" and "▼" buttons at the same time (the red dot flashes quickly 3 times) to switch to solar mode. Then press and hold the "▲" button for 3 seconds to switch the red dot scale.
When the CR1632 battery is exhausted, it will automatically start to solar mode.
